obb — 3D bounds op

• Data kinds: points → primitive

• Call: import pcseg; pcseg.obb(points) -> 'dict' (or ops3d.get("obb"))

Usage

Oriented bounding box by PCA.

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• hull_bounds — py -3.11 examples_3d/hull_bounds.py

Ops the type connects to (they accept primitive as input)
